SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 537,847, dated April 23,1 see. Application led January 28, 1895. Serial No. 536.484. (No model.)

To @ZZ whom, it may concern;

Be it known that I, ROBERT S. OsBoRNE, a citizen of the United States, residing at Muscatine, in the county of Muscatinefand State of Iowa, have invented a new and useful Spring Bed-Bottom, of which the followingis a specification.

This invention relates to spring bed bottoms; and it has for its object to provide a new and useful construction of spring bed bottom that will entirely obviate sagging or settling at any one point. f To this end the main and primary object of the present invention is to construct a bed bottom having the necessary spring to provide for the yielding and easy support of a mattress, while at the same time being so constructed as to provide for the equal distribution throughout the entire area thereof of any weight placed thereon, so that wherever the weight is placed on the bottom the full benefit of the spring of the entire bed bottom will be secured.

With these and many other objects in View, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the draWings:-Figure 1 is a plan view of a spring bed bottom constructed in accordance with this invention. Fig. 2 is a central longitudinal sectional view thereof. Fig. 3 is 4 detail in perspective of a pair of the reversely and elliptically bowed spring-wire links. Fig. 4 is a similar view of one of the transverse bottom Wires.

Referring to the accompanying drawings, 1 designates a rectangular bed bottom frame essentially consisting of the opposite parallel side rails 2 and the transverse head and foot rails 3 and 4, respectively connecting opposite ends of the rails 2, and in the present invention, the head rail 3, is supported on the upper sides of the side rails 2, in a higher plane than the foot rail 4. The bed bottom frame 1, forms a support for the herein described spring bed bottom, and arranged transversely of the frame 1, are a series of parallel transverse bottom wires 5. The transverse bottom wires of the bed bottom are arranged wires is preferably fastened to the foot rail 4,

of the frame 1, by means of staples or other suitable fastening means 6. The parallel transverse bottom wires 5, are formed of suitable lengths of spring wire and extend across the space between the side rails of the frame 1, and at regularly spaced points the said wires are provided with integral horizontal coils 7.

The parallel transverse bottom wires 5, are

connected by the transverse and longitudinally alinged rows of separate pairs of spring wire links 8. The spring wire links 8, are formed of single lengths of spring wire, and the spring wire links of each pair are reversely and elliptically bowed with respect to each y other in order to impart a spring to the bed botends wit-h engaging hooks 9, that are adapted to engage iu the longitudinally aligned coils 7 of the wires 5, so that the hooks of one pair of links engage with the same coils 7, as clearly illustrated in the drawings. The coils 7, of the transverse Wire 5, nearest the elevated head rail 3, of the frame 1,are detachably engaged by the hooks 10, at one end of the coil springs 11. The coil springs 11, are arranged in a and are provided at both ends with the hooks 10, and the hooks 10, at the outer ends of said coil springs 11, are detachably engaged with the V-shaped loops 12, of a fastening wire 13, secured to one side of a movable tension bar 14, to provide means for connecting the springs and one end of the fabric, formed by the wires 5, and the links 8, with said tension bar. The movable tension bar 14, is su ported on the side rails 2, parallel with the head rail 3, and is mounted on a series of bolts 15, iitted within the head rail and provided at their inner ends with the adjusting nuts 16, which provide means for adjusting the bar 14, to maintain the spring bed bottorn properly stretched or at the proper tension. At this point it is to be noted 'that by reason of the elevation of the rail 3, and the IOO S 5 transverse row at oneend of the bed bottom adjacent bar 14:, the proper shape or conformation is-given to the bed bottom to entirely obviate a sagging or settling thereof.

At the opposite sides of the spring bed bottom are arranged the side lacing wires 17, that are laced through the longitudinally aligned coils 7, at the opposite sides of the bed bottom and are fastened to the side rails as at 1S, to provide a yielding connection between the sides of the bed bottom and the frame supporting the same.

Changes in the form, proportion and the kminor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention. f

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is-

1. In a spring bed bottom, the combination of' a series of parallel transverse bottom wires provided at regularly spaced points with horizontal coils, and transverse'and longitudinally aligned rows of separate pairs of spring Wire links, the spring wire links of each pair being reversely and elliptically bowed with respect to each other, and provided at their opposite ends with engaging hooks engaging the longitudinally aligned coils of the transverse wires, substantially as set forth.

2. In a spring bed bottom, the frame having an elevated head rail, a series of transverse parallel wires, one of which is fastened to the foot rail of the frame and all of which are provided at spaced points with horizontal coils, separate pairs of spring wire links connected at their ends with the longitudinally aligned rows of horizontal coils, side lacing wires fastened to the side rails of the frame and laced through the coils at the sides of the frame, and an adjustable connection between the elevated head rail and one end of the fabric consisting of the transverse wires and the links connecting the saine, substantially as set forth.

3. In a spring bed bottom, the combination of the frame, a series of transverse parallel wires one of which is fastened to the foot rail of the frame, and all of which are provided at spaced points with horizontal coils, separate pairs of spring wire links having hooks at their ends engaging the longitudinally aligned horizontal coils, a movable tension bar adj ustably supported at one side of the head rail of the frame, a fastening Wire attached to said tension bar and provided with a series of loops, and a transverse row of coil springs provided at both ends with hooks respectively engaging the loops of said fastoning Wire and the horizontal coils of the adjacent transverse Wire, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
